Title: Warning device for distance between vehicles
Inventor: HOSOKAWA KIYOSHI
IPC: B60W30/00
Filed: 1989-12-05
Abstract: PURPOSE:To maintain a proper distance between vehicles in accordance with a variation state by setting up the distance between the vehicles to a long distance when sudden braking is frequently applied within a prescribed time, similarly setting up the distance to a long distance when the lapse of time from the start of driving exceeds a prescribed time and when the succeeding vehicle enters into the set distance, sending an alarm to the vehicle. CONSTITUTION:When a reset switch RS is depressed, the lapse of time from the depression and the frequency of sudden braking operation with pressure exceeding a prescribed level within a unit time are counted by a limit threshold changing means 12. When the lapse of time exceeds the prescribed time, e.g. 3 hours, the distance between the vehicles is changed so that inter-vehicle distance limit threshold is increased to set up a value corresponding to driver's fatigue generated with the lapse of time. When the frequency of sudden braking exceeds a set value, e.g. 3 to 5 times, the distance is similarly changed so that the threshold is increased to set up the value corresponding to the driving state. When the set value is exceeded, an unsufficient distance between the vehicles is informed to the driver and a dangerous signal is sent to maintain safety driving.

Title: Identification element
Inventor: BUERUNAA OBURETSUHITO
IPC: G06Q20/34
Filed: 1989-12-06
Abstract: PURPOSE: To prevent the wrong use by electrically isolating a time-dependent element from other circuits and controlling, for example, a data input line to invalidate the function of a discrimination element for a certain time after input of a wrong code. CONSTITUTION: A comparator 5 compares the actual discrimination code sent from, for example, a keyboard with a nominal discrimination code stored in the discrimination element and generates an error signal in the case of non- coincidence of its character string. A control element 4 is connected to a charging element 3 and generates an output signal at the time when a capacitor is charged. Connection to the discrimination element is affected for a certain time by this signal. For example, the data input line of the discrimination element is controlled by the output signal from the control element 4 as the influence, and as a result, it means that the function of the discrimination element is invalidated for the certain time. Thus, the wrong use is prevented.

Title: Read only optical disk
Inventor: KAWANAKA RYUTA
IPC: G11B11/10
Filed: 1987-12-16
Abstract: PURPOSE:To improve the readability and writability of recording information and C/N by forming a magnet layer in which a magnetic direction on a disk substrate is fixed, and simultaneously, laminating a layer consisting of a superconductive material on the magnet layer. CONSTITUTION:A magnet layer 14 of a thin film is film-formed on a disk substrate 12, a superconductive material layer 16 is film-formed on the upper layer part of the magnet layer 14, and thereafter, an outer surface is covered with a protecting layer 18. At the time of executing a recording to a recording medium, a laser beam is projected on the superconductive material layer 16, and when it is heated to a temperature or above at which the crystal construction is destroyed, an irradiated part is permanently made into a constant conductive condition. Consequently, the magnetic flux of the magnet layer 14 of a lower layer is leaked from such a part, and a non-irradiated part, on which the laser beam is not projected, is magnetic-shielded by the Meissner effect of the superconductive material layer 16. For such a reason, by leaking magnetic flux and the magnet shielding in the parts except it, a recording discrimination can be attained. Thus, a strong magnetic field can be obtained, and the C/N can be improved.

Abstract: PURPOSE:To remedy a defective memory cell so as to improve the yield of a memory circuit by replacing the defective memory cell with a standby memory cell in the unit of one piece by switching the connection between a row-direction address line with a column-direction address line by means of a switching element. CONSTITUTION:When three pieces of memory cells become defective over three rows and three columns in normal memory cells, the defective cell X1 is replaced with a standby memory cell by switching a row-address line A1 to a column- address line B1 by means of a switching element S31 and the row B1 to a row- address line C2 by means of a switching element S21, and then, the row C2 to the row-address line A1 by switching a switching element S22 to another element S32. When the connection between row-address lines and column-address lines is switched by means of switching elements in such way, defective memory cells can be replaced with standby memory cells in the unit of one piece. Therefore, defective memory cells can be remedied without increasing the number of standby memory cells and the yield of this memory circuit can be improved.
